This driver has been developed as a separate module starting from the similar sdhci-esdhc-imx.c. Reasons for a separate sdchi-esdhc-mcf driver: - m68K architecture does not support devicetrees, so modifying sdhci-of-esdhc.c that is devicetree-related adding platform data seems not appropriate, - clock-related part, has to be implemented specifically for mcf5441x family (see esdhc_mcf_pltfm_set_clock()), - this is a big endian cpu accessing a big endian controller, but about sdma, this controller does not support hw swap, which needs to be handled with specific code, - some other minor differences but mainly to avoid risks on tweaking inside largely used imx driver. Adding just a small size ColdFire-specific driver, with benefits in a further less risky maintenance.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
